BOILER.

SPECIFICATION forming para of Letters PatentNo. 42?'77,OO2,fc`latel January 24, 1888.

v Application filed October 12, lSS'. Serial 2l6,0 64. (No model!) N Beit known that I, AMASAWORTHINGTON,

4a citizen of theUnited States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Boilers, of whichlthe` following isa full, clear, andexact description.

My invention relatesto an improvement in supports for the forward end of a water-tube boiler; and the purpose of my invention is to combine strength and lightness witha provision for the taking up ofthe expansion ,and contraction which shall permit the withdrawal of a pair of tubes without necessitating the dis# placement of the others, as well as to permit all the tubes to be withdrawn from the boiler without displacement vof the steamdrums,

To this end my invention consists in the construction and arrangement of parts, all as hereinafter more fully described and claimed.

Inthe drawings, Figure 1 is a front eleva-v tion of the interior of afurnace, showing the ofl part of the boiler,showing the rearsupport;

and Fig. 6, a vertical vcross-section on theline rc .fvof Fig. 5, showing details.

A is the furnace-wall; B, the steam-drums; C, the water tubes.; D and E, the bends and headers, respectively, connecting the watertubes together; F, the bends connectingthe upper series of the water-tubes with the lsteamdrums; G, the downtake and shell-connector,

and H the bends -connecting thev downtake with the boiler-'tubes at the rear, all the fore' each of said supports Iis formeda groove, I',

"which theends s may be inserted.

for the purpose hereinafter described, These, Asupports'are made ofk T or angle ironand setV into they side walls of the furnace.

r'Bolted at each end to the side pieces is they upper cross-plate, K, in the forni of al 'platey 7provided 'with'ap'ertures T, to receive the pro-v jecting reduced ends s of the steam-drums B. In place of simple apertures4 a sleeve, r, may

be castinto the rear part of the p'lat einto The lower cross-piece or bearing-beam, L,

f is made of angleiron and bolted to the cornergroove I ofthe vuprights I I and provides a Jsupport therefor. AThe headers E occupy the spacer between the upper plate, K, and-bearing-beam L, resting upon the latter, and are caused to engage with the upper plate, lK, to

prevent displacement by means of locking-y plates 0inserted into thegrooved tongues o',

formed on the uppermost headers.

The 'upper series of `bends f are of the same' construction as those of the front yand back of the boiler throughout, and are providedY with projecting perforated ears to receive T-bolts n,

the headsof which are inserted intoA recessed i, lugs m, formed on the end of the drums B. f

For further security, recessedlugs maybe formed' on theI drums B to receive. T-bolts e', passing through the plate K.

To afford perfect security against forward and backward displacement, I find it advisableto' set the side frame, I, and the ends ofthe plates KV and L into the wall Vof the furnace, althoughit is kobvious' that any tendency to displacement ,is largely vovercome by the securing medium p afforded inthe platep and lower support, L,

resting on the furnace-wall.

At the rear @faq the rfurnace a plate, K', is providedkat the point of communication between the-downtake-shell G and the upper bends, I-I, provided with the;

necessary aperturesifor the insertionr of a bend J `and header and set into the wall of the furnace.

Displacement is prevented by a locking-plate v similar to that employed betweenJthe. upper front plate and headers, which engages the rear upper'headers and rear supporting-.plate through recessed lugs formed onthe headers.y

Ico

Y Itwill be seen that by the use of my invention a means is provided for supporting the drnnisindependently ofthe boiler-tubes, which may be withdrawn and replaced without displacement ofthe drum or connections or affecting the security of the support provided there- W'hat I claim as new, and desire to secure by Letters Patent, is-` 1. A supporting-fra1ne for the forward end of a water-tube boiler,eonsisting, in combination, ofthe upper eross-pieee, K, side supports, I I, supporting the cross-piece K, and having formed upon their lower` ends grooves I', 4and lower cross-pieee, L, provided upon its inner` end with a rib, l', to engage with the groove formed in the lower end ol' the supports I I, substantially as and for the purpose set forth,

In testimony whereof I havehereunto set my 3o hand this r7th day of October, A. D. 1886.
